Across New Zealand, thousands of people have taken part in protests sparked by the death of African-American man George Floyd at the hands of police. Further rallies and vigils are planned in Australian cities this week. The gatherings are happening as both countries maintain social distancing and just as New Zealand marked 11 consecutive days of zero new cases of COVID-19. Monash University infection prevention researcher Philip Russo reflects on the dilemma of large gatherings while we are trying to manage the pandemic.

At times of crisis, trustworthy media coverage matters more than ever. But the pandemic has changed the media landscape in New Zealand, bringing both unprecedented audience growth and dire economic threats and closures. AUT media expert Wayne Hope charts the latest bold move which saved New Zealand’s largest newspaper publisher and online news site and he proposes a strategy for a comprehensive media reconstruction.

And in non-pandemic news, we learned this week that New Zealand sits atop the ancient remnants of the largest volcanic outpouring on Earth. Geophysicists Simon Lamb and Tim Stern — both at Te Herenga Waka Victoria University of Wellington — explain how they used speed patterns of seismic waves to reveal New Zealand’s deep geological history.

You’ll find lots more to read in this week’s newsletter, including about a call for a commissioner for older people and New Zealand’s long-awaited NZ$700 million package to address freshwater pollution.
